Figure 4. (A) A graphical representation of the process to create a bendable TENG using a composite film of porous PDMS/MXene alongside an electrode made from laser-induced graphene (LIG)^[59]. (Published by Elsevier in 2019). (B) A schematic representation of a versatile TENG apparatus. It includes an SEM image that illustrates the upper and lower electrodes crafted from silver nanowires (AgNWs), with an inset showing AgNWs dispersed in a solvent (scale bar: 1 μm). Additionally, an optical microscopy image of the composite friction film is shown, with an inset displaying the solvent for the composite (scale bar: 200 μm). This is accompanied by a graphical comparison of the absorbance levels between a pure PDMS film and a PDMS/Mxene composite film^[60]. (Published by Elsevier in 2021). (C) A diagrammatic depiction of the NDL-TENG^[61]. (Published by Elsevier in 2022).
